Subject: Rollup merge of #79310 - jyn514:fold-item-cleanup, r=GuillaumeGomez
X-Git-Url: https://git.lizzy.rs/?a=commitdiff_plain;h=f74b223e195082af56fca1c886d08ccf3377db33;p=rust.git

Rollup merge of #79310 - jyn514:fold-item-cleanup, r=GuillaumeGomez

Make `fold_item_recur` non-nullable

This gets rid of a bunch of `unwrap()`s and makes it a little more clear
what's going on.

Originally I wanted to make `fold_item` non-nullable too, which would
have been a lot nicer to work with, but unfortunately `stripper` does
actually return `None` in some places. I might make a follow-up moving
stripper to be special and not a pass so that passes can be
non-nullable.

Found while working on https://github.com/rust-lang/rust/issues/76998.
